shape and so constructed as to maintain in proper position a suitable nut or other support through which a set screw is passed for normally retaining such annulus or col'lar in place upon a shaft orrother similar element.

My invention also includes the process of making 'an annulus or shaft collar of this type; the nut for the set screw being placed.

1n proper position relatively to thel parts oom risingthe annulus or collar preparatory to tie iinal compression and 'securing of the same into the desired form.

My invention is fully shown in the accompanyi'ng drawings, in which:

Figure 1, is a erspective view of one Jform of annulus or eol ar embodying my invention; Fig. 2, is a view of the parts of the annulus or collar shown in Fig. 1, before assembling; Fig. 3, is a sectional view, .taken on the line a-a, Fig. 4; Fig. 4, is a sectionalview, taken on the line b-b, Fig. 3; Fig.y 5, is a view similar to Fig. 1, showing another form of annulus or collar; Fig. 6, is a view of the parts of the structure shown in Fig. 5, before assembling; Fig. 7, isa sectional view, taken on the line c-c, Fig. 8; Fig. 8, is a sectional view, taken on the line d-d, Fig. 7, and Figs. 9- to 38, inclusive, are sectional views illustra'ting modified forms of shaft collars or 'annuli embodying my invention.

All of the structures forming the subjeet of my invention comprises sections or blanks of sheet metal pressed into shape to form a hollow member, and sodisposed as to provide mutual connection and support, and to confine in proper relative position a suitable nut for thezset Screw employed with such collars.'

In the structureshown in Fig. 1, the collar com rises annular members 1, 1, of similar size an shape, which have been previously formed from sheet metal blanks by suitable dies. These sections are providedwith half round registering notches 2 in their inner and outer webs roviding for the passage of' a set screw 3, said set screw being arranged to en-` y gage a nut or other threaded support 4 which is mounted within the hollow space formed by the sections; being confined by suitablev means in proper relative position to the reg-' istering lnotches of the sections forming the collar. l y To maintain the sections 1,1, of the form of collar shown in Fig. 1, in the proper osition with relation to each other, I provi e an annular securing sleeve 5 disposed against theinner web or wall oi said sections; such ysleeve being apertured at 6 for the passage of the set screw 3, and in order to confine the sections 1,1, in position by said sleeve, I bead or turn the edges 7 of the same against the outer edge of the inner web of the sections 1, in the manner clearly shown in the drawings, such action binding the sections together and. holding them against displacement. If de- `sired, the sleeve 5 may be brazed or otherwisepermanently secured to the sections 1,1. In the present instances, the sections 1,1, have their shar corners rounded or beveled. This securing s eeve 5 is preferably formed into the necessary shape from a flat strip; the meeting edges of which may or may not be secured by brazing or other desirable means.

The nut or support 4, through which the set screw passes, is laid adjacent the secy sections forming the shell' by means of a suitable ings.

In the form of structure shown in Figs. 5', 6, 7 and 8, a dierent type of annulus orV shaft collar is illustrated, in which two mem# bers, L-shaped in cross-section, are combined together to form an annulus or collar. These sections are indicated at 1a, 1a, and are secured together in the manner clearly shown in the drawing. The side web oi the outer member is abutted by the annular web of the inner structure, while the annular web of the punch, as clearlyT shown at S in the drawouter structure is turned over against the' wall of the inner structure, which has been previously slightly beveled or beaded to per- V- ing a contour the reverse of the section 1 t mit such action. The nut is mounted between the sections previously to assembling the same together, and it is held either by the projections formed by the punch marks 3, or by displacing the metal of the shells against the same. This form of the annulus or shaft collar, as will be noted, is made of two sections only.

The subject-matter of my invention may be embodied in a very large number of structures, of 'which the several views of the drawings are clearly illustrative. With the exception of those which are riveted after assemblage, notably Figs. 14, 25, 34 and 35, they are all made in the manner described with reference to the structure shown in Figs. 1 to 8, inclusive.

Fig. 9, shows a form of annulus or collar, comprising` two sections or shells 1b, which are conned together by an internal annular sleeve 5. Fig. 10, shows annular sections 1", of similar size and shape, confined by an external sleeve 5a. Fig. 11, shows sections 1d, of similar size and shape, confined by an ex'- ternal sleevea. In this instance, the sections 1d have an inner flange 9. Fig. 12, shows a structure comprising sections 1C, of similar size and shape, which have their meeting edges brazed at the points 10. Fig. 13, shows sections 1e, of similar size and shape, confined by internal and external securing sleeves 5 and 5a, respectively. Fig. 14, shows a structure comprising sections 1", the inner meeting faces of which abut, while their outer meeting faces are provided with lugs 11, which interlock with each other. These sections are further secured together by rivets 12. Fig. 15, shows a structure, in which sections 1g are provided having abutting inner edges ,-which sections have outwardly projecting flanges 13 confined by a securing sleeve 5h. Fig. 16, shows sections 1h, both of which have outwardly projecting flanges 14 and 15 5 the latter being turned over the former. Fig. 17, shows Lshayed sections 1i; the edges of the walls of one section being beaded over the other, as shown at 16. Fig. 13, shows a structure having L- shaped sections 1k, in which the cylindrical part of one section abuts the side wall of the other; such sections being secured iirplace by beading the outer section over the inner, as shown at 16a. Fig. 19, shows a single section 1m, having its side walls turned over to form flanges 17, and confining an inner sleeve 50. Fig. 20, shows a single section 1, with an inner sleeve member 5d holding the same inrelative position; such sleeve having side flanges 13 against which the walls of the section 1n abut. Fig. 21, shows a single section 10 with a side plate 19 applied thereto; the inner cylindrical portion of the section being beaded over said side plate at the point 16h. Fig. 22, shows a single section 1P; havshown in Fig. 20, and having an external securing sleeve 5e with fianges 1S against which the side walls of the section abut. Fig. 23, shows sections 11, U-shaped in cross-scction, which fit into each other; the outer section being turned down over the inner at the point 16". Fig. 24, shows sections 1", of similar size and shape, which are confined together by brazing at the point 10. Fig. 425, shows a structure made up of flanged side plates 1*, and internal and external sleeves 5f and 5g, respectively. This structure is further secured together by rivets 12. Fig. 26, shows a structure comprising sections 1L, having external abutting flanges 20, with an internal securing plate 5", and an external securing plate F 1*; the latter having a grooved rib 21. to accmnmodate the flanges 20. Fig. 27, shows a single member 1, L- shaped in cross-section, having a raised portion 22 to accommodate the nut, and carrying an internal sleeve 5i holding the latter in place. Fig. 2S, shows a U-shaped structure 1", having an external plate 5 supported upon lugs 23 carried by the side walls of such. section. Fig. 29,- shows a pair of' similarly sized and shaped sections 1' fitting inside and outside each other, and beaded over at their diagonally opposite corners, as indicated at 16d. Fig. 30, shows a single section 1X, having inwardly disposed flanges .2-1. Fig. 31, shows a structure comprising sections 1y and 1; the section 1y having a flanged portion 25, against which a portion of the section 1Z abuts; while diagonally opposite therefrom, the section 1Z is turned down over the section 1y, as indicated at l6. Fig. 32, shows a single U-shaped section 1*l with its walls disposed outwardly,indicated at 1M. Fig. 33, shows a single member 1l, L-shaped in cross-se tion, and having an external member 22*l for aN-ying the nut. Fig. 34, shows two sections 1, L-shaped in cross-section, the radial walls ol' which abut and are confined together by rivets 12'). Fig. 35, shows two L-shaped sections 1id with the edges of their cylindrical portions abutting, and being confined by the rivets 12". Fig. 36, shows two sections 1, of similar size and shape, having their cylindrical portions abutting, and having outwardly disposed flanges 20 confinedby an external sleeve 5 having a grooved rib 21 to accommodate said fianges. Figs. 37 and 33, show cylindrical structures 1 and 1%', respectively, U- shaped in cross-section; the latter having an inwardly disposed flange 26 at one sidewall of the same.

In completing the annulus or shaft collar, the sections of the same are assembled in a suitable manner, the nut being properly positioned and maintained in such position by means of the set screw, or a suitable pin, which is passed through the apertures of the several sections and then the sections are subjected to pressure while confined between suitable dies whereby the securing means, such as compressing the metal of such sections with respect to each other, or the em ployment of the sleeve 5, are applied, and the sections of the annulus or collar thereby locked against displacement. Before removing the set screw or pin, the nut is confined in place by displacing the metal of the sections relatively thereto, or by the punch immediately after removing the completed collar from the press.

I may, if desired, braze any and all of the abutting faces of the several forms of structures shown herein, and I may further harden the side wall or face of the respective collars which comes opposite the work. In all instances the strip used as the inner securing collar or sleeve may be made of'flat metal with its abutting ends brazed or not as desired, and while the outer securing sleeves may also be made of such metal, the abutting edges of the same are preferably brazed.
